Food & Drink

Synbiosis, with its colony imaging expertise has pioneered the development of automated colony counting since 1985 to bring you three world leading colony counters - the ProtoCOL 3, Protos 3 and the aCOLyte 3. Within these ranges you’ll find the perfect colony counting system to suit your budget and the complexity your food and drink testing demands.

Rapid colony counts

You can use a ProtoCOL 3, Protos 3 or an aCOLyte 3 in microbial enumeration for safety testing applications including microbial limits testing and media quality control to rapidly provide you with a precise total viable count (TVAC). These systems are flexible and can accurately count pathogenic bacteria (Staphylococcus, Listeria and Enterobacteriaceae), yeast or moulds on spiral plates, pour plates and membrane filters.

Precise colour differentiation

With the ProtoCOL 3 and Protos 3 you’ll find unrivalled colour differentiation technology. So if you’re safety testing milk and milk formula to determine the presence of pathogenic coliforms (Salmonella, E.coli or Enterobacter sakazakii) on selective agar, ProtoCOL 3 and Protos 3 can do this quickly and easily. The systems' colour analysis is so impressive it can even give you precise counts of Campylobacter colonies on a dark agar background.

Time saving analysis

With the simple to use software in Synbiosis colony counters, you can automatically distinguish true colonies from food debris and bubbles in the media or membrane grid lines. The software saves you hours by effortlessly providing precise images and count data in seconds, which you can store and go back to time after time.
